On the Estimation of Areal Windspeed Distribution in Tropical Cyclones with the Use of Satellite Data.

摘要

An attempt is made to determine whether the areal windspeed distributions in tropical cyclones can be estimated by use of two satellite data parameters: (1) the low-level convective cloud band crossing angle relative to tangents to concentric circles centered on the eye,and (2) the infrared temperatures from the 10.5-to-12.5micrometer channel. These two parameters plus the 'ground truth'winds were all derived for 128polar coordinate grid points (16azimuths and 8radii). Coincident values of the variables were evaluated statistically first by linear regression and afterward by multiple screening regression.
